> how soon, by your clock, will the torpedo reach the black hole horizon?
The torpedo is likely to accelerate due to gravitational pull from the black hole. So the torpedo will reach the black hole horizon faster than in 1 hour.
However I will not see how torpedo reaches that black hole horizon, because the light informing me about the torpedo movement will come to me slower and slower [depending on how close that torpedo is to the black hole event horizon]. When torpedo is almost at the event horizon, the light from that torpedo will be moving back to me at almost zero speed, so I will have to wait almost indefinitely in order to see it.
